cpu_clock: CPU Clock

In shinra-dev/okcpuid: Interface to the cpuid library

Description

A utility to look up some basic performance information about the CPU.

Usage

cpu_clock(milis = 200, quad_check = FALSE)

Arguments

milis	The amount of time in miliseconds the clock test should run for. Recommended range is 10-1000.
quad_check	logical; if TRUE, the average of a best of four runs is returned.

Details

There may be a large difference between the CPU clock as reported by the OS and as discovered by the small test. Modern operating systems keep the CPU clock scaled down to save power, and scale them up as needed.

Value

Returns a list containing:

ncores	Number of "cores" (physical + logical).
clock.os	The CPU clock as reported by the OS.
clock.tested	The CPU clock determined from a small test.
peak	Theoretical peak floating point operations per second.
